From Kim Rupert:The origin of the Francis Dubreuil/Barcelona confusion is identical to that for Irene Watts and Pink Gruss an Aachen. Bob Edberg imported Francis Dubreuil from Peter Beales. He rooted a plant for The Huntington, which he gave me to take to Clair Martin when I went out to volunteer. I did. That plant should still be in the Tea and China bed at The Huntington. I gave cuttings to Carolyn at Sequoia from this FD. I rooted them for the Huntington Plant Sales, and the one which still grows in what's left of my garden. The FD at Ashdown came from this plant, also.Barcelona had grown in the gardens at The Huntington for decades. My plant, and that given to Ashdown and Sequoia, came from that plant, also. I still grow that plant, too. Both varieties are own root, and have been kept separate so as to prevent confusion. In my climate, there is no difference. I can also tell you when grown under plastic, at Sequoia, budded on a tree stock, the FD blooms are VERY much like those of Oklahoma. Try it, it's very interesting.
